Igwe ọkụ seramiiki bụ ngwaọrụ na-ewepụ okpomọkụ site na ngwa eletrọnịkị na-ekpo ọkụ nke ngwa eletrik.Ka ọ dị ugbu a, mpempe akwụkwọ seramiiki alumina a na-ejikarị, akwụkwọ seramiiki nitride aluminom, mpempe akwụkwọ seramiiki silicon carbide.

Alumina seramiiki mpempe akwụkwọ: Ọ nwere arụmọrụ dị elu nke okpomọkụ, conductivity thermal: 24W / MK, okpomọkụ dị elu / nrụgide nrụgide dị elu, okpomọkụ na-ekpo ọkụ, nkwụsị ọkụ ngwa ngwa.Na mgbakwunye, ọ nwere usoro dị mfe na kọmpat, obere nha, elu dị larịị, ike dị elu na ọ dịghị mfe imebi, acid na alkali corrosion resistance, inogide.

Aluminium nitride ceramic mpempe akwụkwọ: Agba bụ isi awọ na-acha ọcha, elu dị larịị, enwere ike ịhazi ya n'ụdị ma ọ bụ nha ọ bụla, dị mfe iji na wụnye.Igwe ọkụ seramiiki a nwere ezigbo ikuku thermal, conductivity thermal bụ 7-10 ugboro nke alumina seramiiki mpempe akwụkwọ, nwere ike iru 180W elu, ọrụ mkpuchi ọkụ eletrik ya kwụsiri ike, dielectric mgbe niile na ọnwụ ọkara dị ala, nwere ike idi ogo Celsius 1800 na anaghị emetụta arụmọrụ nke ngwaahịa.Site na mmepe ngwa ngwa nke ngwa elektrọnik, ọchịchọ maka ngwaahịa eletrọnịkị ma ọ bụ ihe inyeaka na-abawanye ụba, na ntinye ngwa ngwa nke ngwaahịa a dị ka ihe dị elu thermal conductivity aluminum nitride ceramic sheet dị ka matrix ma ọ bụ nkwakọ ngwaahịa na-abawanye ụba n'ahịa. .

Silicon carbide seramiiki mpempe akwụkwọ: Ọ bụ ihe nchebe gburugburu ebe obibi akwụkwọ ndụ akwụkwọ ndụ, ọ bụ nke microporous Ọdịdị, na otu unit ebe nwere ike ịbụ ihe karịrị 30% porosity, ukwuu na-amụba okpomọkụ dissipation ebe na ikuku kọntaktị, welie okpomọkụ dissipation mmetụta.N'otu oge ahụ, ikike okpomọkụ ya dị ntakịrị, nchekwa okpomọkụ nke onwe ya dị ntakịrị, enwere ike ibufe ọkụ ahụ n'èzí ngwa ngwa, isi njirimara nke seramiiki okpomọkụ: nchebe gburugburu ebe obibi, mkpuchi na nrụgide dị elu, nkwụsị ọkụ na-arụ ọrụ nke ọma. , iji zere ozuzu nke nsogbu EMI.Ọ nwere ike dozie nsogbu nke nchịkwa okpomọkụ na ikpo ọkụ na ngwá electronic na ụlọ ọrụ ngwa ngwa.N'otu oge ahụ, ọ na-adabara nke ọma maka obere ike ọkụ na ọkara.Oghere imewe na-eleba anya na ọkụ, mkpa, obere na obere ngwaahịa, nke nwere ike inye nkwado teknụzụ na ngwa maka mmepụta na mmepe nke ngwaahịa eletrọnịkị.
